安装Docker 1.12

Kubernetes 1.6还没有针对docker 1.13和最新的docker 17.03上做测试和验证，所以这里安装Kubernetes官方推荐的Docker 1.12版本。

yum install -y yum-utils
yum-config-manager \
    --add-repo \
    https://docs.docker.com/v1.13/engine/installation/linux/repo_files/centos/docker.repo
yum makecache fast

查看版本：

yum list docker-engine.x86_64  --showduplicates |sort -r
docker-engine.x86_64             1.13.1-1.el7.centos                 docker-main
docker-engine.x86_64             1.12.6-1.el7.centos                 docker-main
docker-engine.x86_64             1.11.2-1.el7.centos                 docker-main

安装1.12.6：

yum install -y docker-engine-1.12.6
